摘　　要：基于重量法等温吸附实验,在实验中都常会遇到等温吸附曲线在高压阶段下拐即“倒吸”现象,。通过4种不同方法相互比较,最终采用以吸附相密度为变量的三元Langmuir模型来作为地质矿物重量法等温吸附的校正方法。Based on the isothermal adsorption experiment by gravimetric method,the phenomenon of"inversion"of isothermal adsorption curve at high pressure stage is often encountered in experiments.By comparing four different methods,the ternary Langmuir model with the density of the adsorbed phase as a variable was used as the correction method for isothermal adsorption of geological minerals by gravimetric method.
